When selecting a certain version from an experience page as supported via CMS-13201, that version should be rendered in the channel manager

Selecting an explicit version of the experience page (or perhaps in general a document) should work for both HST rendered websites as for SPA rendered websites (also with token authentication). The versioned document is ONLY allowed to be rendered in this way IF the user is doing a channel mgr preview request (for site ftl pages and thus for PageModelAPI output)

When the CM includes a querystring to the URL, then even if the URL is for an SPA, the SPA will invoke the PMA with the querystring. The querystring could include something like:

?br_render_uuid = uuid 

to render a specific document variant for the current URL (which is thus only allowed for channel mgr preview requests (for now)

Note

When a version from version history is rendered via something like '?br_render_uuid' which is NOT the most recent version, the Channel Mgr will have containers for the XPage that are locked (or not even shown as containers, what do you prefer cdekort?)
